Claims. 1

This invention appertains to novel and useful improvements in seats particularly useful in theatres, athletic contests, stadiums, churches, auditoriums and the like.

An object of this invention is to provide removable seat means journaled in a base member.

Another object of this invention is to provide means for resiliently biasing said seat means to a certain predetermined selected position.

A further object of this invention is to provide limiting means for association with said seat means, for the purpose of retaining the said seat means in a selected position while operative.

A still further object of this invention is to provide an extremely simple, durable, dependable and efiicient device of the nature described which is commercially feasible, practical and which lends itself well to commercial manufacture and common shop practices.

Ancillary objects and features of novelty shall become apparent to those skilled in the art, in following the description of the preferred embodiment of the present invention, illustrated in the accompanying drawings, wherein:

Figure 1 is an elevational front view of the preferred form of the present invention;

Figure 2 is an elevational front view of the invention disclosed in Figure 1, showing the seat portion thereof partially removed;

Figure 3 is a fragmentary sectional view of the invention disclosed in Figure 1 and taken substantially on the line 33 thereof and in the direction of the arrows, and;

Figure 4 is an elevational view of the detail of construction taken substantially on the line 4--4 of Figure l and in the direction of the arrows.

Referring now in detail to the illustrated preferred embodiment of the present invention, like reference characters are used throughout to indicate similar elements.

This invention has been developed in order to provide a device which is silent in operation, dependable and practical. It is within the purview of the present invention to provide a device of this nature which utilizes less space than the conventional theatre seats yet offers the same advantages of said conventional seats along with other improvements. It occasionally becomes necessary to reupholster seats or remove the same for other purposes. Accordingly, a seat has been provided herewith which is extremely simple and which may be easily removed from its journaling elements.

A base portion including a back rest It and the usual side walls [2 and I4 respectively is provided for the purpose of supplying the improved seat thereon. The said improved seat is composed of a conventional seat member is which may be upholstered and which may have springs therein, if so desired.

Lugs l8 are suitably secured to the undersurface of the said seat I6 by any conventional means such as screws, weldings, rivets or the like. Each of the lugs l8 are preferably composed of a shank portion or pivot pin 20 terminating in a transverse cross member or arm 22. Housings 24 are rigidly secured to or, if desired, integral with each of the said sides l2 and I 4. Inspection of Figure 3 shows the general configuration of the said housing means 24. There is disclosed .a body member having inturned abutments or' stops 26 and 28 respectively adjacent the periphery thereof. A slot 30 is received in each of said housing means 24 for the purpose of receiving the lug means I8 therein. Also, this same slot 30 is utilized in removing the said lug means Hi from the housing, in order to remove the seat I6 from its base member. Means for resiliently urging the said cross member 22 to a selected predetermined position is provided. The preferable construction of this means is a simple coil spring associated with each of said housings and each of said lugs 18. As is seen from an inspection of Figure 3, an aperture 34 is provided in the cross member 22 of the said lugs while another aperture is provided adjacent the said abutment 28. The said spring means 36 is removably received within the aperture 34 and the above mentioned aperture 38. A small lug or screw 40 might be utilized in association with the last mentioned aperture 38 for the purpose of insuring a firm seat for the said spring 36. It is noted at this point that it is within the purview of the present invention to utilize the large aperture 42, formed in the construction of the said abutment means 28. If this last mentioned aperture 42 is utilized the terminal portion of the said spring 36 is adapted to extend therethrough, thence extend around the lug or anchor means 38.

In operation, the seat It may be lowered as viewed in Figure 1, thereby extending the cross member 22 in abutting relation with the said abutment means 23 and 28 respectively. Of course, this construction limits the pivotal travel of the said lug means I 8. Then, when it is desired to raise the said seat it, pressure is released from the upper surface of the said seat, permitting the resilient biasing means 36 to carry the same (seat) to its raised position. In removing the said seat Hi from its associated journaling elements,

the resilient biasing means 36 is simply slipped from its anchored position at 38 and 4-0 and the seat, including the lugs I8, is lifted from the slots 30.

Due to the extreme mechanical simplicity of this invention, further description thereof is deemed unnecessary. It is understood that variations as to size and shape may be made herein Without departing from the spirit of the invention. Accordingly, limitation is sought only in accordance with the scope of the following claims.

Having described the present invention, what is claimed as novel and improved is as follows:

1. A seat construction comprising a base having side walls, a housing secured to each of said side walls, slot means in each of said housings, a seat having pivot pins removably received in said slots, means for resiliently biasing said pivot pins, means for limiting the rotative travel of said pivot pins, apertures in said housings, said resilient biasing means comprising springs detachably received in said apertures and reacting on said pivot pins.

2'. A seat construction comprising a base having side walls, a housing secured to each of said side Walls, slots in each of said housings, a seat having pivot pins received in said slots, means for resiliently biasing said journal means, means for limiting the rotative travel of said pivot pins, a cross member secured to each of said pins detachably received through said slots in said housings, apertures in said housings, said resilient biasing means comprising springs detachably secured to said cross members and in said apertures.

3. A seat construction comprising a support including side walls, a seat, means for pivotally mounting said seat on said side walls including a housing attached to one of said side walls, a slot in said housing, a pivot pin carried by said seat removably disposed in said slot, an arm attached to said pivot pin and disposed in said housing, and a spring secured to said arm and said housing constantly urging said pivot pin to rotate said seat to its raised position.

4. A seat construction comprising a support including side Walls, a seat, means for pivotally mounting said seat on said side walls including a housing having a top wall and substantially flat back wall, a slot in said top wall and said back wall, a pivot pin carried by said seat, an arm fixed to said pivot pin, said pin and said arm being removably disposed in said slot, stops disposed in said housing and engaged by said arm to limit the pivotal travel of said arm.

5. The combination of claim 4 and a spring attached to said arm and said housing for resiliently biasing said pin.
